2661 Tue Mar 22 13:09:44 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
2663 * coff-mips.c (mips_howto_table): Add entry for new MIPS_R_PCREL16
2664 reloc, used in embedded PIC code.

2684 _bfd_generic_link_add_symbols but also collect constructors and
2685 destructors by name as collect2 does.
2686 (generic_link_add_symbols): New function, like old
2687 _bfd_generic_link_add_symbols but with collect argument.

2704 extended name table.
2706 Mon Mar 21 12:28:19 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
2708 Support for link_order types which generate relocs in order to
2709 support -Ur in the linker.
2710 * linker.c (generic_link_add_symbol_list): Remove bitsize argument
2711 from call to _bfd_generic_link_add_one_symbol.
2712 (_bfd_generic_link_add_one_symbol): Remove bitsize argument.
2713 Don't pass bitsize to constructor call back. Pass BFD_RELOC_CTOR
2714 instead of bitsize to add_to_set call back.
2715 (_bfd_generic_final_link): Account for link_order relocs when
2716 allocating space for relocations. Handle them in link_order loop.
2717 (_bfd_generic_reloc_link_order): New function.

2735 allocating space for relocations. Handle them in link_order loop.
2736 (ecoff_link_write_external): Set the storage class of a defined
2737 linker created symbol based on the section it is in. Correct
2738 bfd_link_hash_weak case to use .sc rather than .st.
2739 (ecoff_reloc_link_order): New function.
2740 * coff-alpha.c (alpha_bfd_reloc_type_lookup): Handle

2751 Sun Mar 20 09:24:36 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2753 * bfd/som.c (som_begin_writing): Fix thinko (off by one error).
2755 * som.c (bfd_section_from_som_symbol): Only to do the value
2756 comparison for function symbols within executables.
2758 * som.c (bfd_section_from_som_symbol): Renamed from
2759 som_section_from_subspace_index. Pass in a native SOM symbol.
2760 For executables, iterate through the sections to find out
2761 which contains the symbol's address rather than using the
2762 symbol_info field. (symbol_info has a different meaning for
2763 dynamicly linked executables.)
2765 * trad-core.c (trad_unix_core_file_p): Don't pass abfd to
2768 * som.c (som_begin_writing): Fix braino (one call to align
2769 space/subspace data was done unconditionally rather than
2770 just for executables.)
2772 * som.c (som_begin_writing): Align text in all executables to
2773 make HPUX kernel happy. Fixes strip/objcopy for shared
2776 Sat Mar 19 07:06:59 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2778 * som.c (som_begin_writing): Account for alignment needs of
2779 subspaces too when writing executables. Never request a negative
2780 bss size. Fixes some problems with demand paged executables,
2781 still having problems with pure executables and shared executables.
2783 Fri Mar 18 19:12:47 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2785 * trad-core.c (trad_unix_core_file_p): Call bfd_zmalloc not
2786 bfd_zalloc for rawptr, because later on we may call free, not
2789 * bfd.c (struct _bfd): Add cisco_core_struct to tdata union.
2790 * libbfd.c (bfd_read, bfd_seek): Add comments regarding errors.
2791 * cisco-core.c: New file.
2792 * Makefile.in: Change accordingly.
2793 * configure.in: Recognize cisco_core_vec.
2794 * config/m68k-aout.mt (SELECT_VECS): Add cisco_core_vec.
2795 * targets.c: Add cisco_core_vec.
2796 * bfd-in2.h: Rebuilt.
2798 Fri Mar 18 18:13:49 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2800 * som.h (som_copyable_section_data_struct): New structure
2801 containing all the private section information which needs
2802 to be copied from input section to output section during
2804 (som_section_data_struct): Remove several fields now in
2805 som_copyable_section_data_struct. Make the space and
2806 subspace dictionaries be pointers (to save space when
2807 only reading objects).
2809 * som.c (bfd_som_set_section_attributes): Now returns a boolean;
2810 some references changed. Allocate a copyable data stucture if
2811 none exists. Store info into the copyable data structure.
2812 (bfd_som_set_subsection_attributes): Likewise.
2813 (som_is_space, som_is_subspace, som_is_container): New functions.
2814 Use these instead of directly accessing private data.
2815 (som_prep_headers): Allocate space and subspace headers here.
2816 Fill in some fields in the space/subspace headers from the
2818 (som_bfd_copy_private_section_data): Only copy the stuff
2819 that we really need to make objcopy and strip work. Allocate
2820 the copy_data structure for the output bfd before copying.
2822 * som.h (struct som_exec_data): New structure to hold exec
2823 info that must be preserved when running objcopy/strip.
2824 (struct somdata): Add new "exec_data" field and accessor
2825 macro. Add some comments on how the various fields are used.
2826 (som_section_data_struct): Make is_space and is_subspace bitfields.
2827 Delete unused subspace_index. All references now use the
2828 target_index field within the section structure itself.
2830 * som.c (make_unique_section): Delete unused declaration.
2831 (som_bfd_copy_private_bfd_data): New function.
2832 (som_object_setup): Allocate space for and save exec information
2833 that needs to be copied during objcopy/strip.
2834 (som_mkobject): Do not allocate space for a file header here.
2835 It is not used when only reading SOM objects.
2836 (som_prep_headers): Allocate space for and attach a file header
2837 to the output bfd. For executables, use the saved system_id
2838 value rather than trying to guess the right value. Do not abort
2839 wwhen setting file_hdr->entry* for executables.
2840 (som_begin_writing): For executables, set the exec_entry and
2842 (som_copy_private_backend_section_data): Always return a value.
2844 * libhppa.h (PA_PAGESIZE): Define.
2846 * som.c (SOM_ALIGN): Define.
2847 (som_begin_writing): If writing an executable, initialize all
2848 fields in the exec header to zero. Update fields in the exec
2849 header as sizes of loadable subspaces are computed. Carefully
2850 preserve alignments when building executables. Actually write the
2851 exec after all the fields are filled in.
2853 * Better long-filename handling. Reads SOM ABI compliant extended
2854 names, but doesn't quite write compliant extended names yet.
2855 * som.c (som_slurp_extended_name_table): Delete function. The
2856 generic code will handle things correctly.
2857 (som_slurp_armap): Seek to the beginning of the next member.
2858 (normalize): New function.
2859 (som_bfd_ar_write_symbol_stuff): Take the size of the extended
2860 name table into account when computing the file offsets in the
2861 SOM dictionary. Make sure to align to an even boundary.
2862 (som_write_armap): Initialize the checksum to zero.
2863 (ar_maxchars): Fix. Opps.
2865 Fri Mar 18 20:35:24 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
2867 * aoutx.h (reloc_type_lookup): Handle BFD_RELOC_CTOR on a 64-bit
2868 machine. Handle BFD_RELOC_SPARC13 and BFD_RELOC_SPARC_BASE13.
2870 Thu Mar 17 18:26:46 1994 Ken Raeburn (raeburn@cujo.cygnus.com)
2872 * bfd-in.h (BFD_VERSION): Use @VERSION@.
2873 * Makefile.in (bfd.h): Replace it with contents of VERSION file.
2874 * bfd-in2.h: Regenerated.
2876 * trad-core.c (trad_unix_bfd_is_local_label): Fixed typo where
2877 this was also named trad_unix_bfd_copy_private_bfd_data.
2879 Thu Mar 17 10:37:07 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2881 * aoutx.h, elfcode.h, coff-alpha.c, bout.c, ecoff.c, ecofflink.c,
2882 elf32-hppa.c, elf32-mips.c, linker.c, som.c, sunos.c: If malloc(0)
2883 returns NULL, it is not an error. It's possible that some of
2884 these checks are not necessary (because the size can never be
2885 zero), but putting in the checks is the conservative thing to do
2886 in light of the fact that some of these malloc calls replaced
2887 unchecked alloca calls, in which a zero argument would work fine.
2889 Thu Mar 17 11:44:45 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
2891 * osf-core.c (osf_core_bfd_copy_private_bfd_data): Remove
2892 duplicate definition.
2893 (osf_core_bfd_is_local_label): Define.
2895 * reloc.c (bfd_generic_get_relocated_section_contents): Don't fail
2896 if malloc (0) fails. bfd_canonicalize_reloc returning 0 is not a
2897 failure indication, it merely means there are no relocs.
2899 * elfcode.h (NAME(bfd_elf,write_object_contents)): Don't use space
2900 after NAME, since SunOS /bin/cc can't handle it.
2902 Wed Mar 16 16:43:33 1994 David J. Mackenzie (djm@thepub.cygnus.com)
2904 * netbsd386.c (N_SET_FLAGS): Don't nuke the machine id field.
2905 From sukes@glue.umd.edu (Tasuki Hirata).
2907 Wed Mar 16 07:55:54 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2909 * aoutf1.h (4 places): Use a simple #if on ARCH_SIZE, rather than
2910 all that convoluted stuff with NAME, CAT3, etc. The convoluted
2911 stuff broke for SunOS4 /bin/cc (due to DEFUN elimination, I guess).
2913 Wed Mar 16 00:02:05 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2915 * som.c (som_prep_for_fixups): Detect section symbols based
2916 on either the lack of private data or the symbol flags. Do not
2917 munge section symbol names anymore -- they no longer confuse GDB.
2918 (som_begin_writing): Leave space for an exec header if writing
2920 (som_slurp_symbol_table): Recognize both forms of section symbol
2921 names "L$0\002" and "$<FOO>$". Change the name of "L$0\002"
2922 section symbols to be the name of the section they represent.
2923 Debugging symbols begin with "L$0\001", not just "L$".
2925 Tue Mar 15 22:58:28 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2927 * bfd-in2.h, libbfd.h, libcoff.h: Rebuilt.
2929 * bfd-in.h (JUMP_TABLE): Add new entries to the jump table
2930 for bfd_copy_private_section_data, bfd_copy_private_bfd_data,
2931 and bfd_is_local_label.
2933 * targets.c: Add new entries to the bfd_target structure.
2935 * bfd.c (bfd_copy_private_bfd_data): New definition.
2937 * section.c (bfd_copy_private_section_data): New definition.
2939 * syms.c (bfd_is_local_label): New definition.
2941 * libbfd-in.h (bfd_generic_is_local_label): Declare.
2943 * libbfd.c (bfd_generic_is_local_label): New function.
2945 * *-core.c: Provide default definitions for new functions in
2946 the target vector which all point to bfd_false.
2948 * aout-target.h, coffcode.h, elf32-target.h elf64-target.h, ieee.c
2949 libaout.h, libecoff.h, nlm-target.h, oasys.c, srec.c, tekhex.c
2950 Default new vectors for copying private backend data to bfd_true.
2951 Default new vector for determining if a symbol is a local label
2952 to bfd_generic_is_local_label.
2954 * som.c (som_bfd_copy_private_section_data): New function.
2955 (som_bfd_is_local_label): New function.
2956 (som_bfd_copy_private_bfd_data): For now default to bfd_true.
2958 * elf32-hppa.c (hppa_elf_is_local_label): New function.
2960 Tue Mar 15 23:55:47 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
2962 * cf-m68klynx.c (CALC_ADDEND): Use _bfd_m68klynx_howto_table.
2964 Tue Mar 15 04:41:13 1994 David J. Mackenzie (djm@rtl.cygnus.com)
2967 Replace DEFUN and DEFUN_VOID with K&R-style function definition.
2968 Indent some of them to GNU standards.
2970 * aout32.c, archures.c, core.c, cpu-h8300.c, cpu-i960.c,
2971 cpu-m68k.c, cpu-m88k.c, cpu-mips.c, cpu-vax.c, ctor.c, demo64.c,
2972 elf32-hppa.h, gen-aout.c, host-aout.c, init.c, libhppa.h,
2973 libieee.h, liboasys.h, newsos3.c, som.h, stab-syms.c, sunos.c:
2974 Update copyright years.
2976 Mon Mar 14 11:41:23 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2978 * som.c (som_prep_for_fixups): A relocation involving the section
2979 symbol for the *ABS* section is really a relocation involving
2981 (som_slurp_symbol_table): Do not set BSF_GLOBAL or BSF_EXPORT for
2982 undefined symbols. Correctly distinguish between debugger symbols
2983 and section symbols.
2985 * som (setup_sections): Set SEC_DEBUGGING and the section attributes
2986 for spaces and subspaces.
2988 * som.c (som_bfd_count_ar_symbols): Fix typo.
2990 * som.c (som_object_setup): Set EXEC_P, D_PAGED, WP_TEXT, and
2991 HAS_RELOC based on the object's magic number.
2992 (make_unique_section): Delete function. BFD and its users are
2993 prepared to handle multiple sections with the same name.
2994 (setup_sections): Allocate space on the BFD's obstack to hold
2995 section names. Use bfd_make_setion_anyway rather than the
2996 obsolete make_unique_section.
2997 (som_prep_headers): Choose the correct SOM magic number based
2999 (som_bfd_fill_in_ar_symbols): Return false, not NULL on error.
3001 Sat Mar 12 09:46:09 1994 Ian Lance Taylor (ian@cygnus.com)
3003 * elf32-ppc.c: Renamed from elf32-powerpc.c.
3004 * nlm32-ppc.c: Renamed from nlm32-powerpc.c.
3005 * Makefile.in, configure.in: Corresponding changes.

3009 * elf32-powerpc.c: Extensive changes to update to preliminary ABI.
3011 Fri Mar 11 00:34:59 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
3013 * sunos.c (sunos_read_dynamic_info): Assume that dynamic info
3014 is always located at the start of the data section to allow
3015 recovery of the dynamic info from a stripped executable.
3016 * ecoff.c (ecoff_styp_to_sec_flags): Handle STYP_PDATA, STYP_XDATA
3019 Wed Mar 9 17:17:53 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
3021 * libbfd-in.h: Remove alloca cruft. It was missing some necessary
3022 cruft (like the #pragma alloca for AIX).
3023 In addition to that problem, the C alloca calls xmalloc, which
3024 means checking for being out of memory can't work right. The
3025 following changes remove all uses of alloca from BFD.
3026 * hosts/solaris2.h: Remove alloca cruft.
3027 * som.c: Replace alloca with a fixed size auto array.
3028 * aoutx.h, elfcode.h, nlmcode.h, bout.c, coff-alpha.c, ecoff.c,
3029 ecofflink.c, elf32-hppa.c, elf32-mips.c, linker.c, reloc.c, som.c,
3030 sunos.c: Replace alloca with malloc and appropriate error checking and

3376 bother processing them.
3377 (b_out_get_relocated_section_contents): Set reloc_done. Assert

4080 The sparc (and possibly other?) NLM format requires a different
4081 way to write exports, so add a write_export field to the backend
4082 data (and set it to NULL for everything but the sparc).

4248 sym_filepos as well.
4249 (ecoff_get_extr): Use ifdmap instead of ifdbase.

4326 * nlm32-gen.c, nlm64-gen.c: Removed. All nlm targets are
4327 different, so there is no point to providing a generic one.
4328 * libnlm.h: Don't bother to check for nlm_backend(bfd) being NULL
4329 in the backend accessor macros; that should no longer be possible.
